Vector Photonics has been invited to ECOC to present a paper showing how PCSELs can deliver datacentre bandwidths of 800Gbs and over.

Vector Photonics has been invited to present its paper, ‘PCSELs at multiple wavelengths for high-bandwidth communications’ at the ECOC exhibition and conference in Basel, Switzerland, from the 19th – 21st September. ECOC is the premier, European exhibition for the fibre optic communications industry, showcasing the latest developments from across the world. The invitation to present is both a privilege and a testament to the importance Vector Photonics’ all-semiconductor PCSELs (photonic crystal surface emitting lasers) play in resolving many of the challenges faced by the datacoms industry as bandwidth requirements increase – namely power consumption, latency, physical connection size and costs. Senior executives from companies such as NVIDIA, ADVA, Infinera, Huawei, BT and IBM will be presenting alongside Vector Photonics, as well as numerous universities from around the world.

Dr. Calum Hill, Principle Development Engineer at Vector Photonics, who will present the paper said, “Hyperscale datacentres require at least 800Gbs data transmission interconnects to keep up with growing demand for cloud services. This is at the limit of current, pluggable, optics technology. Vector Photonics’ PCSELs more easily enable co-packaged optics solutions, where the optical functionality is integrated onto the ASIC (application-specific integrated circuit) to improve overall system performance, whilst reducing system energy consumption and cost.

“The CW (Continuous Wave) PCSELs, required for these bandwidths, operate in the O-band as a high-power, seed laser for multiple data channels. Their surface emission gives far better power scaling and beam divergence than conventional solutions, as well as simpler silicon photonics fabrication. Furthermore, the structure of a PCSEL is not dependent on the base epitaxy used, allowing PCSELs to be made at multiple different wavelengths for different communication needs.”

Calum will present the Vector Photonics paper at the ECOC on 21st September 2022 at the 8th International Symposium for Optical Interconnect in Data Centres.
